I don't have the feeling that google finance is live and kicking. I think it's one of those product that will disappear soon. There are lots of broken feeds like:
I actually went to google finance where I could get live price feed when yahoo and my bloomberg terminal had 15min delays. Now even yahoo has live feeds too.
I work in finance. It's a last resort. It should be front page, but it was ignored for too many years. I think I see it once or twice a year, now.
